You can see what your competitors are advertising for free, and legally, using two public tools: the Meta Ad Library, which shows the ads a business is running across Facebook and Instagram, and the Google Ads Transparency Center, which shows ads served by a verified advertiser on Google. Used well, they tell you what offers your rivals are pushing, how long they have kept an ad running, and which formats they have bet on, in about 30 minutes and with no paid tool.
This guide explains how to use both tools, how to read the signals without fooling yourself, and what you should and should not do with what you find.
Is it legal and ethical to look at competitor ads?
Yes. These libraries exist precisely because platforms and regulators wanted advertising to be publicly visible. You are looking at ads that were already shown to the public, using official tools. What crosses the line is copying someone’s creative, text or images, impersonating their brand, or trying to access private data such as their spend or targeting through unofficial means. Study the strategy, then make your own work. Reusing a competitor’s copy word for word invites both legal risk and a weaker ad.
How do you use the Meta Ad Library?
Go to the Ad Library from Meta’s website, choose the country you care about and the category “All ads”, and then search either by business name or by a keyword. Some practical tips:
- Search by Page name first. Look up your five closest competitors one at a time, then look at the overview of everything they are running.
- Search by keyword for the wider market. A phrase like “free quote” or “book a call” surfaces businesses you may not have considered rivals.
- Check the start date. Each ad shows when it began running. An ad that has been active for many weeks or months is more likely to be working, because most advertisers turn off what loses money. It is a hint, not proof.
- Filter by platform and format. See whether they favour video, static images or carousels, and whether they use Instagram placements.
- Note the number of versions. Many near-identical ads under one message usually mean the advertiser is testing variations of a winning idea.
In the European Union and some other regions, the library also shows extra transparency details for certain ads, such as targeting and reach for ads about social issues, elections or politics, and, under EU rules, some information about commercial ads as well. What is shown differs by region and changes over time, so check what is available for your market rather than assuming.
How do you use the Google Ads Transparency Center?
Google’s Ads Transparency Center lets you search for an advertiser by name or website and see the ads they have run, where they ran, and in what format. You can filter by region, time period and format, such as text, image or video. It is most useful for:
- Seeing whether a competitor advertises on Google at all, and in which countries.
- Reading their text ads, which show how they position the offer, the headline wording and their call to action.
- Spotting video ads on YouTube that you might otherwise never come across.
It will not show you keywords, bids, budgets or conversion data. For those, you would be guessing, so do not pretend otherwise. Search results pages themselves also show you current ads for the terms you care about: search your own main keywords from different devices and locations, and read what appears at the top.
What should you look for?
Do not just collect pretty ads. Build a short comparison grid with one row per competitor and columns for the things that reveal strategy:
| Question | What it tells you |
|---|---|
| What is the main offer? | Discount, free trial, free quote, guarantee, lead magnet |
| Who are they speaking to? | Audience, pain point, or life stage they address |
| What is the hook? | The first line or first three seconds of a video |
| What proof do they use? | Reviews, numbers, certifications, before and after |
| What action do they ask for? | Buy, book, call, sign up, learn more |
| How long has it run? | A rough signal of what is working |
| Where does the click go? | Landing page, product page, form, WhatsApp |
Click through to the landing pages too. The ad is only half of the funnel, and a competitor’s landing page often shows their pricing logic, their lead form length and their follow-up promise.
What can you conclude, and what can’t you?
This is where people go wrong. The libraries show you activity, not performance. A few cautions to keep your analysis honest:
- Long-running does not always mean profitable. Some advertisers forget to turn things off, and some campaigns serve brand goals rather than direct sales.
- Short-running does not mean failed. A seasonal promotion is meant to end.
- You cannot see their results. They might be spending heavily to learn nothing. Copying a rival’s mistake is easy.
- A large number of ads can mean testing or chaos. Look at whether the ads share a clear message.
Treat what you find as a source of hypotheses to test in your own account, not as proof of what works. If a theme such as “free consultation” appears across four competitors, ask whether it is table stakes in your market, and whether a different angle might stand out.
How do you turn the findings into better ads?
- Find the gap. If every competitor leads with price, test leading with speed, guarantee or expertise.
- Answer the objection. If rivals avoid mentioning a common concern, such as hidden costs, you can address it head-on.
- Beat their hook, not copy it. Write your own opening that fits your brand voice and promise.
- Improve the landing page. If their page is slow or confusing, a clean one is a real advantage. See our guide on matching ad message to landing page.
- Brief your creative team or agency with a one-page summary of what you saw and what you want to try. Our template for briefing a creative agency on paid ads shows what to include.
How often should you check?
Once a month is enough for most small businesses, and more often during peak seasons, when rivals change offers quickly. Keep a simple document with dated screenshots and notes, since ads disappear once they are turned off and you may want to compare later. In Q4, for instance, watching the countdown to Black Friday gives you a clear view of when competitors switch on promotions, which feeds directly into your own timing plans such as the Black Friday ad account prep.

Common mistakes
- Looking only at big brands. The most useful competitors are the ones fighting for the same customer in the same place, even if they are small.
- Ignoring the audience. An ad aimed at a different customer type may not apply to you.
- Collecting without deciding. End each review with two or three concrete tests, otherwise the research goes nowhere.
- Chasing every trend. One competitor trying a new format is a data point, not a mandate.
A 30-minute competitor ad review
- List your five closest competitors and search each in the Meta Ad Library (10 minutes).
- Search the same names in the Google Ads Transparency Center, and run your top three keywords yourself (8 minutes).
- Fill in the comparison grid for the most interesting ads and open two landing pages (7 minutes).
- Write down three things that are common, one gap and two tests you will run (5 minutes).
Competitor ads will not tell you what is working for them, but they will tell you what the market is saying to your buyers right now. Your job is to say something clearer, more specific, or more honest.
